In practice a tapered blank of sheet metal isinserted between the peripheries of the male and ien'ie e cut-out or tongueiormrng d1es,the former being actuated by the revolution of the driven shaft 2 1, which drives the shaft of the female die through the lnterlneshing ,gears 31 and 3-2.

are usually made stoutc-r, and the wires are usually secured thereto by wrapping or otherwise, and hence are not equipped with retaining tongues. 1 have shown. the several sets of male and female dies duplicated on their respective shafts, at 34-, I5 and so, save that the female dies are not formed with the central chambers The dies of these further diil'er from those hoiore described only in that their co-oper ive portions are of greater cross sectional area in lieu of the tongue-ior ning di s i. provide iced rolls 37 and 38 mounted sin'iilarly to the tongue-forming dies.

1 claim my invention:

1. A fence-post machine comprising operating rotary dies constructed to low cut-outs in a portion of the face of a fence post blank, era-operating rotary (lli l'i ior crimping or corruga'iing such post blank longitudinally after the first nwntioncd dies have acted thereon, and means ljor throwing said first mentioned rotary dies out oi cooperative relation While a portion of the blank is passing between them.

2.
